Also, this date is wrong; at 9m35s Steve Conway and Kevin Nelson discuss the closure of the Irish free radio stations which happened at the end of 1988.
Therefore, this should be 31st December 1988.
Chris Cooper and Gavin Ford certainly weren't on board (they started in Autumn 1989). Caroline Martin wasn't on board either (she returned to the ship on 2nd January 1989 after a two-year absence).
I do hear contributions from Dave Asher, Neil Gates, Nigel Harris, Frances Hayes, Kevin Nelson and Mike Watts around midnight (some are just talking and laughing in the background), however Radiopedia refers to this as a Steve Conway programme.
